CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. provisional application No. 60/639,867, filed on 28 Dec. 2004, and entitled METHOD FOR SIMULTANEOUS COMMUNICATIONS MANAGEMENT, the disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to the presentation of multiple communications on a single device and more particularly management of multiple communication data streams on a single output device.

BACKGROUND OF THE INVENTION

The recent advances in data throughput for mobile wireless communication devices provides a myriad of opportunities to add functionality and provide new services not possible with slower data rate equipment. Consequently, the data rates necessary to support streaming video and voice simultaneously are being realized thereby allowing the video functionality in portable wireless handsets.

Some devices provide video streaming both to and from the device using a display to present the video image and a built-in or attached camera to store and then transmit the images to the intended recipient. With lower data rate devices, small file size images and video clips may be received and or transmitted by the wireless commutation device. Third generation wireless devices provide video streaming to and from a single intended recipient.

Other devices provide dispatch operation mode for voice interchange in two way radio, half duplex or simplex format that allows for two-way conversations but one user at a time. One example has been termed a push to talk mode similar to a walkie-talkie where the push of a button opens the microphone for transmission. However these communication modes are available for voice and do not provide full duplex communications.

Management however of multiple communication streams such as during group call or a conference all is limited by the size of the display and the formats in which the communications are being presented. Presenting communications to the user when multiple formats, such as a combination of voice only and video communications is used, makes presenting the communications awkward as displays on portable deices limit the amount of information that may be presented to the user at a given time.

What is needed is a method for presenting multiple communications on a single device that is intuitive and easy to determine which communication stream has the active conversation. The various aspects, features and advantages of the disclosure will become more fully apparent to those having ordinary skill in the art upon careful consideration of the following Detailed Description thereof with the accompanying drawings described below.

DETAILED DESCRIPTION

Before describing in detail the particular data management method and apparatus in accordance with the present invention, it should be observed that the present invention resides primarily in combinations of method steps and apparatus components related thereto. Accordingly, the apparatus components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

A method and apparatus for presenting communications in a wireless communication device is disclosed. The method comprises presenting a plurality of communications concurrently with at least one output device of a wireless communication device. The plurality of communications may be a plurality of video streams of a conference call for example which are concurrently received at the device. The method further comprises formatting the plurality of communications on the at least one output device as a function of the number of communications of said plurality of communications and of at least one condition.

FIG. 1 is an exemplary communication device 100 having a display 102 for presenting communications top the user. In this exemplary embodiment, four streaming images are presented on the display 102 in real time. A first video 104 a second video 106, a third video 108 and a fourth video 110. In this exemplary embodiment, the video images are presented in a four square or 2×2 matrix arrangement however the first video 104 is formatted with a larger size than the other three video images in response to a characteristic of at least one of the video images or condition. Also in this embodiment, there may be more or less than four participants in the communication or group call type event but the exemplary streaming of four videos is shown. Other participants, not shown in video format in the call may only be communicating by voice. The other participants may not be displayed as configured by the user i.e. the sender may override configuration setting of the receiving device as discussed above. For example, the sender can select an option configuring the communication to be presented by the receiving device in audio only format even though the receiving device is requesting to present the communication as a video. The method would comprise that the sending device determines the format for viewing on the receiving device.

The exemplary electronic device 100 comprises a housing portion 110 and a user interface that comprises at least the display 102 and a speaker 112. The user interface may also comprise an input device such as a keypad 114 or touch pad or the like. In the exemplary embodiment, the electronics device 100 is a wireless communications handset such as a cellular radiotelephone. The display 102 may be an output only display capable of presenting video format information or a combination input output device such as a touch screen display. One input device may be a singe button 116 to activate communications with intended recipients of the communication or a full QWERTY keypad for example. The single button 116 may be a push-to-talk or push-to-video button that initiates or activates communications. When the push-to-video button is depressed, the conference call is initiated. While the plurality of communications is received the push-to-video button may be used to perform a mute/un-mute for example.

The electronic device 100 described herein is a representation of the type of wireless communication device that may benefit from the present invention. However, it is to be understood that the present invention may be applied to any type of hand-held or portable electronic device including, but not limited to, the following devices: radiotelephones, cordless phones, paging devices, personal digital assistants, portable computers, pen-based or keyboard-based handheld devices, remote control units, portable media players such as an audio player (such as an MP3 player) and the like. Accordingly, any reference herein to the device 100 should also be considered to apply equally to other hand-held or portable electronic devices.

FIG. 2 is an exemplary wireless communications handset schematic block diagram 200 comprising generally a processor 210 coupled to memory 220, for example RAM, ROM, EPROM, etc. The exemplary wireless handset also includes a radio transceiver 230, inputs for example a keypad 240, a microphone 250 and video inputs such as a camera 260, and outputs, for example a display 270 for visual output, a speaker 280 for audio output, and other ports, for example power, audio, etc., all of which are coupled to the processor 210. The keypad 240 and the single button 290 are coupled to the controller 210.

In addition, the handset may further comprise video RAM 222, a video driver 225 for processing incoming and outgoing multimedia data. A camera 260 is also coupled to the processor 210 to bring image data, in still or moving format. A coder/decoder (CODEC) 215 is capable of processing audio and video encoded in accordance with the Moving Picture Expert Group (MPEG), such as MPEG-1 Layer 3 (MP3) or MPEG 2 Advanced Audio Coding (AAC) or other formats of the like.

The various elements of the exemplary wireless handset, for example the processor, memory, inputs, outputs are disposed generally in a housing. The display is often mounted on the housing whether it is a part of a one piece assembly, or a multiple piece assembly where the housing elements move relative to one another. The housings may also include a keypad or keypads. The location and arrangement of these exemplary wireless handset elements is only an exemplary application and is immaterial to the presentation of the communications received at the device, which are discussed more fully below.

One exemplary method is illustrated in FIG. 3 by a flowchart showing the presentation of a plurality of communications on a wireless communication device. In step 302, each device to be communicated with is selected on the wireless communication device 100 through a software menu. It is to be understood by skilled artisans that the selection of contacts through the use of a user interface may be accomplished in numerous ways. The operation used to select the contact is immaterial to the present invention. In this exemplary embodiment, the devices to be communicated with are selected from a contact list. A group list may also used to select the devices to be communicated with as it is groupings of contacts from the contact list. A combination of contacts and a group list may also be used.

Once the desired contacts are selected, a call is placed, in step 304 to all desired contact devices and the device establishes communication links therewith. Each contact device that is capable of video communications may stream video from its device to the wireless communication device. The wireless communication device 100 determines 306 the user interface to present the communications by and the configuration to use. The wireless device 100 then presents 308 each of the communications by the determined user interface and configuration on the user interface.

In another embodiment, the wireless communication device 100 receives the calls from other devices accepting a call from each device individually. The conference call may also be established by placing and receiving incoming calls to form the group call. In another embodiment, a “video” button (a soft key/menu selection or hard key) or push-to-video button will bring up multiple video images on the display, with all images streaming simultaneously. The user may select through the wireless device 100 or system, manually or automatically, some of the users to be audio only, while others remain streaming video. This may be done via a menu selection, or touch screen on/off (i.e. touch the images to keep, double touch images to send to audio or, revert to a list of users in a menu and choose those for audio or video.

In yet another embodiment, the user may select a “private video” conference with one or more devices already in the group call during the simultaneous video/audio conference. And in yet another exemplary embodiment, the communications may be configured or formatted such that the user may choose between several video streaming talk groups via the wireless device menu or the push-to-video button. The device may configure, manually or automatically, by virtually deleting video or audio users. This may include users who rarely communicate in the group for example or this may include users who have not communicated for a period of time (as determined by system or device). These users (who are still a part of the communications channel) may be virtually added back in if they become active. For example, only three people are dominating the video discussion, so only those three appear on the wireless communication device 100. A fourth person starts talking, and now that streaming image appears with the others on the device 100.

Configuring the presentation of the communications may be based on a formula or threshold taking into account characteristics of each communication. For example, the device 100 may configure to shift an on screen video stream to audio (i.e. there is a formula that determines how much the others are transmitting to decide to show video or audio). For very large talk groups, the presentation configuration may be prioritized based on, phone number, ID, rank, typical past usage—such that 50 video streams do not show up on display all at once.

Another exemplary configuration may be to start all communication in an audio only format, and only add video as discussed above or selected by the user. Other criteria that may be used to determine configuration may be velocity or location such as when in a moving vehicle, only audio is presented. When in a certain location (or velocity) only show certain video, and the rest audio (example, when at home, only audio; when at work, video). The method therefore would comprise for example choosing audio mode only when the device detects a predetermine velocity, rate of acceleration or predetermined location.

In one embodiment the device 100 may reduce resolution of certain streams based the above communication characteristics. For example, one person not talking much starts turning fuzzy or the frame rate slows down. In another exemplary embodiment, the device 100 has multiple displays. Video streaming of a sub group (at least one communication) is presented on one screen, while an alternate sub group (or the rest of the group) is presented on another screen. (example two people video stream to external CLI, while the other four in the group are presented on the first display. In one exemplary embodiment may only seen when the flip is open in a clam shell type communication device.
